2 claims. (c1. 12s- 196) This invention relates to appliances for automobiles, airplanes, stationary engines and the like, and has for an object to provide a device which will take up the vapor trom the gasoline 5 tank as well as from. the oil lter and deliver the same to the intake manifold for the purpose of saving the gas that is usually lost by vaporization from the gas tank and from the crank case.

A further object is to provide a device of this character which will return the oil vapor from the crank case to the intake manifold so that the piston walls and top of the pistons will be lubricated in addition to saving the oil vapor that is usually lost from the oil iilter or breather.

A further object is to` provide a device of this character which will be extremely simple and inexpensive in construction, may be installed on new cars as well as used cars Without extensiver alterations, and will be silent and positive in operation. i

With the above and other objects in view the invention consists in certain novel details of construction and combinations of parts hereinafter fully described and claimed.

In the accompanying drawings forming part of this specification,

`Figure l is a side elevation of an automobile with a portion in section and showing the iml proved device applied thereto,

Figure 2 is a detail enlarged section showing the control valve and pipe connections to the manifold, vacuum tank, gas tank and crank case.

Figure 3 is a cross section taken on the line 3 3 of Figure 2, and

Figure 4 is a cross section through the gas tank cap.

Referring now to the drawings in which like characters of reference designate similar parts in the various views, 10 designates an automobile, 11 the gasoline motor, and 12 the vacuum tank, these parts being of the usual and well known construction.

The device, comprising the subject matter of this invention, comprises a valve casing 13, shown best in Figure 2, having a plug valve 14 therein which is equipped with a crank 15 to move the valve to open or closed position. The valve casing is provided on one side with an extension 16, which is T-shaped in contour. The run of the T-shaped extension is provided with nipples 17 and 18 the former being connected by a pipe 19 to the gasoline tank 20 and entering the top oi the gasoline tank through a modified form of cap 21, which Will later be described. The nipple 18 55 is connected by a pipe 22 to the oil iilter or breath er 23 of the motor. The pipe enters the breather cap 24 which is of the usual construction. Thus gas vapor will be delivered by the pipe 19 from the gas tank to the extension 16 and oil vapor from the breather will be delivered by the pipe 22 5 A short nipple 29 connects the lateral branch of 15 the T-coupling with the casing 13 of the valve. The suction of the motor exerted through the pipe 26 to maintain the vacuum in the vacuum tank will draw the gas vapor and oil vapor through the pipes 19 and 22 and deliver the same to theintake manifold. Accordingly, gas vapor which usually evaporates from the gas tank will be saved and also oil vapor which escapes through the breather will be saved, while at the same time odors which usually escape through the breather will be returned for consumption in the motor.

To provide manual control of the plug valve 14, a push rod 30 is connected at one end to the crank 15 of the plug valve 14 and is led through a suitable opening 31 in the instrument board 32. The push rod is equipped with a knob 33 by means of which the rod may be manipulated to open or close the plug valve. A stop 34 is disposed on the rod tolimit Withdrawal of the rod through the instrument board to the dotted line 35 position shown in Figure'l.

Referring now to Figure 4, it will be seen that the cap 21 is open at both ends and is provided at the bottom with an interiorly threaded nipple 35 which is screwed on to the nipple 36 of the gas 40 tank. The cap is provided `at the top with an exteriorly threaded nipple 37 on to which is screwed the usual cap 38 of the gas tank. A packing 39 is disposed between the cap 38 and the nipple 3'7 to prevent leakage between these parts.

The cap 21 is provided with a lateral nipple 40 to which the rear end of the gas vapor pipe 19 is secured gas tight by a nut 41.

By referring to Figure 3, it will be seen that the plug valve 14 is tapered from end to end and is held gas tight in the valve casing by means of a spring 42 which is conned under tension between a nut 43 on the valve stem 44 and the end face of the casing,

From the above description it is thought that the construction and operation of the invention will be thoroughly understood Without further explanation, except that, in its broad aspect the invention is not confined iso-cars having the fuel tank on the rear as the invention is equally Well adapted to cars having the fuel tank above the motor and dispensing with a vacuum tank, in which case the intakesuction alone can be utilized, as will be understood. Also any type pipes can be used such as rubber, metal, iexible metal covered, etc.

What is claimed is:

1. In combination, an internal combustion motor, a fuel tank, a pipe connected with the intake of the motor, a valve casing coupled to said pipe and provided with a T-extension at its end remote from the pipe, a regulating valve in said casing between its ends, a pipe connecting one end of the T-extension With the top of the fuel tank and a pipe connecting the opposite end of said extension with the crank case breather of the motor.

2. In combination, an internal combustion m0- tor, a pipe connected with the intake manifold of the motor, a lateral pipe entering the rst named pipe, a Valve in the lateral pipe, manually controlled means for opening and closing said valve, and pipes connecting the crank case of the motor and the interior of the top of the fuel tank respectively with said lateral pipe at the end thereof remote from the first mentioned pipe.
